Description for the ADS42LB69
The ADS42LB49 and ADS42LB69 are a family of
high-linearity, dual-channel, 14- and 16-bit,
250-MSPS, analog-to-digital converters (ADCs) supporting DDR and QDR LVDS output interfaces.
The buffered analog input provides uniform input impedance across a wide frequency range while
minimizing sample-and-hold glitch energy. A sampling clock divider allows more flexibility for
system clock architecture design. The ADS42LBx9 provides excellent spurious-free dynamic range
(SFDR) over a large input frequency range with low-power consumption.
